Sierra V-Belt 18-15450, Replaces OMC 914787 and Volvo Penta 960336, 45 Inch Effective Length

The Sierra V-Belt 18-15450 is an aftermarket drive belt built to OEM quality standards for marine gas engine applications, including OMC stern drive and Volvo Penta stern drive setups. It has a 45 inch effective length and a top width of 29/64 inch (11.5mm), matching the dimensions of the original equipment belt it replaces. The belt is constructed with a synthetic fiber fabric cover, a special polyester cord, and a polychloroprene rubber body, giving it high strength against shock loads while keeping stretch low so tension and performance stay consistent over the life of the belt. The rubber compound in the body is formulated to transfer load forces evenly and smoothly to the internal cords, reducing slip and heat buildup during operation. Oil resistance and temperature stability are standard features of this belt's construction, which helps it hold up in the engine compartment environment typical of stern drive installations. The Sierra 18-15450 is designed as a direct cross-reference replacement for OMC and Volvo Penta belts sharing the part numbers listed below, so it installs using the same pulley alignment and tensioning as the original belt without modification.
